ELECTRIC LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 562,398, dated June 23,1896.

Application filed April 2 2, l 8 9 5 To all whom it may concern:

Be it known that I, JOHN C. HENRY, a citizen of the United States,residing in \Vest field, county of Union, State of New Jersey, haveinvented certain new and useful Improvementsin Electric Locomotives, ofwhich the following is a specification.

This invention relates to improvements in electric locomotives.

The main objects aimed at in the construction are to reduce the numberof parts, improve the adhesion, and so assemble the motor that it cannotbe injured by shocks in passing over defective rail-joints. In theordinary motor-truck the wheels follow defective track, and strike thelow joints with a blow. In the invention hereinafter described it willbe observed that the wheels are held in the position the track shouldbe, and one after the other will pass over low joints without evertouching them. It will be evident there is no shock to the motor, andconsequently there is no occasion of cushioning it with springs, as isthe common practice.

The invention further relates to improved means of obtaining adhesion,so that a single motor may be connected to three or more pairs of axlesby a single or double member.

In the drawings, Figure 1 represents in side elevation my improvedelectric locomotive as its outlines would appear when passing over a lowtrack-joint. Fig. 2 represents a plan of same.

A represents the field-magnets of the n10- tor, which is supported bythe truck-frame 0 through the intermediate shafts e c. 7) represents thearmature, which is secured by key or otherwise to the axle f. The axlesf, f, and f have bearings in the rigid frame 0. The wheels are alllinked'together by the rigid connecting-rod h and h. Those rods aredriven from their center by the armature I). To enable the truck todescribe short curves, I prefer to have one of the pair of wheelswithout flanges, as shown at g and cf. To avoid danger of those wheelsleaving the track when rounding curves, I prefer to make their treadwider than the others. Pairs of connecting-rods may be used on eachside; but I prefer the single red, such Serial No. 546,799- (No model.)

as shown, as it reduces the number of wearing parts and cannot cramp incrossing the center, as divided connecting-rods are liable to do whentheir bearings become worn. In the plan View -I have shownconnecting-rods on both sides of the truck. This, however, is notessential. A single rigid rod on but one side will operate all of thewheels. I prefer, however, to have them on both sides, as

'shown, so that in the event of one of them breaking or having hotbearings, it may be removed or the bearings loosened up withoutdisablement. In locomotives the universal practice is to set theconnecting-rods quartering, that is, the driving-pin on one side isplaced one-quarter of the circumference ahead of the one on the oppositeside. The result is they cannot be balanced as a whole bycounterweights. In consequence of this the locomotive has an unsteadymovement. In the locomotive herein described the rods are set inapproximately the same position on both sides, thus enabling the wholestructure to be put in perfect running balance by the use of theordinary counterweights. The same general planmay be used where five ormore pairs of axles are required.

What I claim as new, and desire to secure by Letters Patent, is

1. An electric-motor truck having a rigid frame, two or more wheeledaxles extending across and journaled in the sides of said frame, a motormounted in the frame having an armatureshaft centrally located thereinand extending laterally through hearings in said frame and a track-Wheelon each end of said central or third shaft, substantially as described.

2. An electric-motor truck having a rigid frame, two or more wheeledaxles extending across said frame and journaled in the sides thereof, amotor mounted on the frame and having its armature-shaft extendedlaterally through bearings in the sides of said frame, a track-wheel oneach end of said shaft, a crank-pin on each of the traclcwheels, andside rods connecting'said crank-pins on each side, said rods beingapproximately in the same position on both sides of the truck,substantially as described.

3. A six-wheel truck for electric cars, having a rigid frame, end axlesjournaled in fixed hearings in said frame, flanged Wheels on one of saidend axles, Wide-tread flangeless Wheels on the other end axle, a motormounted on the frame, having its armature-shaft extended laterallythrough hearings in said fra1ne,flanged track-Wheels on the end of saidshaft, and rigid side rods connecting the three Wheels on each side, therods being in approximately the same position on both sides of the IOtruck, substantially as described.

In testimony whereof I hereunto affix my signature in the presence oftwo Witnesses.
